[Arid_gardener] RE: Carpenter Worms in Ash Tree

[Stevens, Brad L]

Thanks for you response.  So basically I trim out the infected wood and
that is about the only treatment available?  Is there a prevention plan
if I can get rid of the infected wood?

Hi Brad, 

Thanks for your question.  Ash trees are especially vulnerable to
damage/death caused by the carpenter worm, the larval form of the
Leopard Moth. Dozens of Shamel ash trees were wiped out on John Wayne's
ranch near Maricopa about 6 - 8 years ago. The problem was thought to be
localized until trees started
dying in the southeast valley near Queen Creek. Now the carpenter worm
has been found in Mesa, Gilbert and Chandler and has recently been
identified in the central Phoenix area. Here is a link to a report by
Dr. Andrew Backhaus on the carpenter worm.  This is a serious problem.

Unfortunately, the holes you see are exit holes where the adults have
emerged, not entered.  The larvae are located deep within the tree,
inaccessible to pesticide treatment. 
 
Here is a link to more information on this insect pest.

best to eliminate them as they are boring into the crouches of the trees
and limbs are breaking.
